This is cognitive processing aimed at mentally representing the core material. This type of cognitive processing selects relevant or needed material. This process processing is developed because of the complexity of material presented. If there is too much essential processing, it means the material is so complex it exceeds mental capacity.

Essential cognitive processing is required to make sense of any given material. For example, a film shown very fast with unfamiliar materials, the student's essential processing would use a great deal of cognitive reasoning in "selecting, organizing, and integrating the words and the images."
